a position yat the rear ofV the hinge-pins.

Thistransfer of weight produces a force' tending to overturn the entire apparatus toward the rear. This tendency is counteracted by the projection' of the base of the lback 1 considerably `ro-the rear `oi the said pivotpins,-so that the center ofgravity of 'the apparatus is 'in front of the. bottom edge of the baek i1.

4is an electric control lswitchand 36 and 37v are two'electric lamps, one at each side of aoy the switch. The front 5 has the openings 38 and 39 through which the lamps maybe seen.

48,149, '50, and 51 shown in. FigjG are' electri-c wires connected to the lamps 36 and 37.'

Alll the wiring system is beneath the lower griddle member6 except the resistor 18,*to which are connected the supply wires and 58. 'Thewires 45 and 58 pass out through the' rear edge of the griddle member 6 and thence through the hollow L- shaped member .'59, thence through the hol- Slow L-shaped lmember 60, and into the rear edge of the griddle member `14. The outer open ends of the members 59y and '60 face eachother, the member 59 having in its end `the circular recess 61 which receives the annular projection 62 on` the end or the mem- -ber 60. The axialcenters of the' pivot pins i H17 Jand the descr'bed'pvotl-ike joint between 7 the members 59 and 166 are ina Str-aight line,

so that when `the griddle member 14 is oscillated, the projection 62 turns in the recess 61 without binding.

On Fig. 5, .itis shownthat the distance between the. hinge-lugs 16 Vis greater than the distance between the outer faces of the hinge-lugs 15, the diiierence between these distances being at least equal tothe length ofy the projection 62. In assembling the griddle member 1 i with the griddle member 6, the hingeelugs Vare yarranged with the lugs 15vbetween the lugs 16, buv lthe hinge-lug 15 which is on the opposite side of the member 59 from the projection 62 is iirst placed close to the adjacent hinge-lug16.V Then the ,griddle member 14 isslid 'so as `to cause Vthe projection'62 to enterthe recess 61. Then the hinge pins '17 are inserted throughthe lugs 16 and screwed into the lugs 15, butfbefore the pin Inearest the lower part ofFig. 5 is inserted a. washer 63 is placed between .the lower hinge members 15 and .16, the washer being as thick vas kthe projection-62 is long.
